The above image is a satellite picture of Cape Cod.
What is most accurate about the past and future of the Cape?
5.
Glaciers built a pile of sand and gravel where rivers cannot sustain it, and the Cape will be
eroded until the hard granite core is exposed, like Acadia.
A.
Glaciers built a pile of sand and gravel that is sustained by longshore sediment drift from the
Hudson and Connecticut Rivers, and the Cape will endure forever.
B.
Glaciers built a pile of sand and gravel where rivers cannot sustain it, and the Cape eventually
will disappear beneath the waves.
C.
The military built the Cape as a “Maginot Line” to stop Russian submarines, and now that the
Cold War is over, doesn’t need the Cape any more and is taking it apart.
D.
The Cape was built by longshore drift from the Hudson and Connecticut Rivers, and will
continue to be nourished in the future.
E.
The Cape is an end moraine attached to a medial moraine, built by the glaciers in an unsustainable
place, and destined to disappear many millennia in the future.

In the picture above, the big W is in ocean water, while the little w is in water in a bay cut off from
the ocean by the bar indicated by the pink dashed arrow. A stream flows toward the bay along the
blue arrow, and coastal bluffs are indicated by the dashed yellow arrow.
What probably happened here?
6.
The low bluffs show that erosion has been occurring as waves hammer the shore, and the bar
shows that longshore transport is moving the sediment from that erosion along the shore.
A.
The low bluffs show that the land is being lowered by tectonic processes, which has formed
the bar and allowed the ocean to flood over the bar and make the bay.
B.
A sinkhole opened behind the beach, and the stream slumped into the hole, leaving the bar. C.
The low bluffs show that the land is being raised by tectonic processes, which has allowed the
ocean to flood over the bar and make the bay.
D.
The Monterey Bay aquarium built the bar to isolate the bay as a holding tank for the narwhals
to be used in their new exhibit.
E.
Longshore drift is important, and moves much sediment. The greater width of the beach across the
mouth of the stream than nearby shows how far waves can go; adjacent to the stream, the waves
must cross the beach during storms and batter the bluffs, making sediment that feeds the longshore
drift. If uplift were occurring, it would have dried the bay, and if subsidence were occurring, the bar
would have been moved underwater. Narwhals would be great in an exhibit, but the aquarium hasn’t
been here.

The jetty above (which is a big wall, and could also be called a groin) was constructed out from
the coast in the state of Washington. The water is shallow very close to the jetty, and deeper as
you move away to left, right, or off the end of the jetty at the lower right.
